At the beginning of the project, inventory will decrease by $16,000, accounts receivables will increase by $21,000, and accounts payable will increase by $15,000. All net working capital will be recovered at the end of the project. The initial cost of the molding machine is $249,000. The equipment will be depreciated straight-line to a zero book value over the life of the project. The equipment will be salvaged at the end of the project creating a $48,000 after- tax cash flow. At the end of the project, net working capital will return to its normal level. What is the net present value of this project given a required return of 14.5 percent
